Question

i) find the value of y that makes quadrilateral fghi a parallelogram.
h g
11y y+40
i f
y =

Explanation:

Step1: Set equal sides (parallelogram property)

In a parallelogram, opposite sides are congruent, so $11y = y + 40$.

Step2: Isolate y (subtract y from both sides)

$11y - y = 40$
$10y = 40$

Step3: Solve for y (divide by 10)

$y = \frac{40}{10}$

Answer:

$4$
